Application November 4, 1954, Serial No. 466,804

1 Claim. (Cl. 2.57--124) This invention relates to an improved pipe ortubing hanger, and more particularly to a device for readily installingheat exchange tubing in ceiling or walls forming a room space.

While tubing hangers for the purpose indicated have been previouslymade, nevertheless they are objectionable from the standpoint of costand the lack of facility with which they may be assembled in relation tothe tubing as well as installed by the ereetor.

Accordingly, one of the object-s of the invention is to provide a hangerwhich is made from suitable strip stock into preformed angular sectionswhich may be readily rolled and punched in simple operations to providea section having fastening receiving openings in one flange and tubingreceiving notches in the other flange. This preformed angular strip maybe sheared into sections of the desired length and assembled about thetubing to provide a nailing or fastening ground at either side thereof.Thus, the present invention provides an assembly for continuous sinuoustubing which may be readily manufactured and assembled, and also easilyinstalled by the workman placing fastenings through a selected one ofthe perforated horizontal flanges to secure the tubing in place.

Another object of the invention is to provide a tubing hanger whichlends itself to standard manufacturing practices in its formation andassembly, thereby providing a relatively inexpensive type of hangerwhich adequately supports the tubing in the wall surface.

With the above and other objects in view which will more readily appearas the nature of the invention is better understood, the inventionconsists in the novel construction and arrangement hereinafter morefully illustrated and claimed.

A preferred and practical embodiment of the invention is shown in theaccompanying drawing in which:

Fig. l is a perspective view of the combined tubing and hanger unit.

Fig. 2 is a detailed cross sectional view on the line 2--2 of Fig. 1.

Fig. 3 is a fragmentary side elevation of the hanger, with the tubingshown in cross section.

Fig. 4 is an exploded fragmentary perspective view illustrating themanner of placing sheared or cut sections of the previously fabricatedbase stock in assembled relation.

Similar reference characters designate corresponding parts throughoutthe several figures of the drawing.

Referring to Fig. 1, the tubing designated generally as A is preferablyof the sinuous type having spaced parallel flights or legs connected byan arcuate bight portion. The hanger is designated generally as B.

The base stock may be of any length depending upon the type of materialselected and may be manufactured by any convenient rolling and punchingprocedure. The relatively long prefabricated and punched angular sec- 2:tion may then be sheared into suitable lengths and assembled aboutthetubing A as shown in the drawings;

As intended to be indicated by Fig: 4, the hanger or frame element B isformed from a continuous strip of stock of angular cross section. Theflange 1 of the stock is provided with a linear series of spacedopenings or perforations 2 while the flange 3 is provided at spacedintervals with the re-entrant notches 4.

Again referring to Fig. 4, it will be observed that the flange 1 may beprovided with fastening receiving openings 2 while the flange 3 may beprovided with the notches 4% As will be apparent from Fig. 2, thenotched flanges 3 and 3 are placed in parallel relation with the edgesof their inner flanges resting in the included angle of the othersection so that the longitudinal edges of each notched flange abut theperforated flange of the adjacent angle member, with the notches 4 and 4in registry about the tubing A. The juxtaposed flanges 3 and 3* may thenbe secured together by spot Welds S to rigidly secure the hanger to thetubing and also maintain the flights of the tubing in properrelationship to obtain adequate diffusion of heat exchange in relationto the wall in which the tubing and the hanger are eventually enclosedin the conventional manner.

It will thus be seen that when the mating angle sections are assembledand spot welded together the notches 4 and 4 securely embrace the tubingand the flanges 1 and 1 having the openings 2 are exposed at either sideof the plane of the tubing B.

When the hanger or supporting frame element and the tubing have beenarranged in the assembly as shown in Fig. 1, a nailing ground or flangeis provided at either side of the plane of the tubing so that no matterwhich side the erector sees fit to secure in the wall, he will have anavailable nailing ground in the form of the perforated flange 1 or itscounterpart 1.. Thus, considerable time and labor are saved ininstalling the combined tubing and hanger, and, since the fastening andreceiving openings 2. are spaced throughout the flanges 1 and 1 atrelatively close intervals, there will be no diiflculty in securing theselected flange to rafters or studding.

The hanger as shown assembled in Figs. 1-3 includes a medial body formedby two flange thicknesses which will securely embrace the tubing, and,at the same time, the perforated nailing flanges project from both sidesof the body and enable the erector to readily nail the hanger fromeither side thereof, to the joist or studding.

From the foregoing it will now be observed that the present inventionhas as its distinctive feature the provision of a tubing hanger whichmay be readily and conveniently made and which in its assembled form inrelation to the tubing provides a unit which may be readily and easilyhandled by the erector during installation which will adequately supportthe tubing in the concealed portion of the wall or ceiling so that, forexample, the tubing and the hanger may both be imbedded in a plastercoat or behind a suitable dry wall sheet.
